The clinical performance of the new viewing station with six CRT monitors (17-inch, 1,024 x 1,280) was evaluated. In the primary interpretation of CT images, time measurements were carried out for eight radiologists. No significant differences in reading time existed between CRT and film in 3 of 4 readers in head CT series, and in 2 of 6 readers in body CT series. Compared with the previous system, the new prototype system achieved an approximately 30% decrease in reading time in both head and body CT studies and could reduce mental and eye fatigue.
